Fashion world power couple Marc Jacobs and Lorenzo Martone have split — for now. “They’ve both been telling people that they broke up,” friends said. Martone shot down rumors this month that he’d moved out of the Chelsea Merchantile apartment he shared with Jacobs, but sources say he’s planning to go soon. Martone wasn’t with Jacobs in Provincetown last week for the wedding of Jacobs’ business partner, Robert Duffy. Jacobs served as best man. A rep for Jacobs said, “We don’t comment on Marc’s personal life.” Martone also declined to comment.
